The verdict
ChatGPT edges out SEMrush by 0.8 points (8.8 vs 8.0) -- a A-tier vs A-tier split that's narrow but real. Not a blowout; both belong on a shortlist. The score gap shows up most clearly in the categories that matter for ChatGPT's strengths, so if those categories are your priority, the lead translates.
Pricing-wise, both tools have a free tier (ChatGPT starts $0, SEMrush starts $0), so you can test either without committing. Compare what each free tier actually unlocks -- usage caps, model access, and feature gates differ a lot more than the headline price suggests, especially as both vendors have tightened limits in 2026.
By use case: pick ChatGPT when everyone. Pick SEMrush when marketing teams and agencies who need one platform for seo, ppc, and content marketing research. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in ChatGPT's lane, the tier-list ranking and the use-case fit point the same direction; if you're in SEMrush's lane, the score gap matters less than the fit.
Bottom line: ChatGPT is the safer default for most readers, but SEMrush is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
